Patented Oct. 1, 1912.

Application filed April 26, 1909, SeriaLNo. 492,155.

To all whom it may concern:

Be it known that I, FRANK ENGEL, a citizen of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented a certain new and useful Improvement in Machines for Pasting Storage-Battery Grids, of which the following is a specification.

My invention relates to pastingmachines and in the form selected to illustrate the invention the machine is particularly adapted to apply paste to the grids or paste carry ng elements employed in storage batterles. These grids may assume various forms, but in the constructionselected for illustration the grid is of open work or skeleton form and adapted to carry the paste in such manner that the two opposite sides will form active surfaces.

The object of my invention is to provide a machine for applying paste to objects typified by such a battery grid, and to this end my invention consists in certain novel devices and combinations of devices which will be hereinafter more particularly described and claimed.

In the form of mechanism chosen for illustrating the invention: Figure 1 is a top plan view of the complete machine. Fig. 2 is an end view thereof looking from the left side of Fig. 1. Fig. 3 is a side elevation of the machine, the paste receptacle and associated parts being shown in section. Fig. 4 is a sectional elevation taken on line 4-4 Fig. 1. Fig. 5 is a perspective view of the preferred form of paste wheel. Fig. 6 is a plan view showing the parts as they appear after the upper cylinder and contents have been removed. Fig. 7 is a plan of one of the charging troughs and connected parts. Fig. 8 is a perspective view of the grid holder and Fig. 9 is a perspective view of a portion of a grid of a form adapted to be pasted by this machine.

Similar numerals refer to similar parts throughout the 'several views.

The paste receptacle consist-s preferably of two castings 10, 10, cylindrical in cross section and arranged end to end in uprightposition upon any suitable base pr stand 12. Atthe side is an opening 13 through which the grid may be introduced to receive the paste. Above and below the opening are paste wheels 14 secured to the shafts 15 preferably by means of threadsrunning in such direction that the resistance of the paste will tend to tighten the wheels in place. The preferred form of paste Wheel is shown in perspective in Fig. 5, the blades 14 being arranged at such an angle that the rotation of the wheel will advance the paste toward the grid. The edges next to the grid serve to scrape off the excess paste from the grid and thus produce plates having uniform thickness and smooth, parallel faces. It is desirable that the outer ends of the blades be braced by a ring 14 which is preferably of such diameter as to fit the cylinder and thus perform the additional function of holding the wheels and the shafts l5 centered within the cylinder. Said shafts are rotated by gearing of suitable construction for example the wheels 16,

rigidly secured to said shafts and meshing ,with pinions'17 driven by bevel gears 18 meshing with a common bevel pinion 19 driven from a band wheel 20. By prefer- .ence said shafts rotate in opposite directions thus producing a peculiarly efficient action of the wheels 14 in applying the paste.

The paste is advanced. toward the paste wheels by means of plungers 23 which fit within the cylinders and surround the shafts 15; In the preferred construction they'arc operated by levers which in the present instance comprises the levers 24 fulcrumed at the stationary pivots 25. The upper one o the levers 24 is operated directly by the piston rod 26 of the fluidrpressure cylinder 27,

while the lower one of said levers is operated indirectly by said piston rod, the motion of said rod being transmitted by the intermediate levers 28, 29 and 30. Lever 30 is fulcrumed at the stationary pivot 31 and the arrangement is such that a movement of the piston rod 26 will cause the plungers to move simultaneously in opposite direct-ions.

The preferred operating fluid in the cylinder 27 is air introduced through a pipe 32 or other suitable duct leading to the top and bottom of the cylinder as best shown in Fig. .2. The flow of pressure medium to raise or lower the piston rod 26 is conl the rotary screw (ll-and is adapted to push trolled by a valve 32 The pressure of the paste on the paste Wheelslt caused by the action of the plungers 23 tends to draw the shafts inward. This tendency is overcome by end hearings on said shafts, these consisting preferably of ball bearing members'35 and 36, the inner member 35 being held stationary by the madoorways in said cylinders.

chine frame and the outer member 36 being screwed to the shaft and there locked by'a lock nut 37. i

The paste is introduced into the cylinder 'preferably through doors 40 located just back ofthe paste wheels. In the form illi. trated, these doors when closed form a portion of the cylinder (see especially Fig. 7') and also act as plungers adapted to move back and' forth in troughs 41 leading to the Said troughs are provided with removable covers 42 to of paste into said troughs. Said icovers may be held closed by any-suitable means such as the latches 43 pivoted at 44 to saidfcove'rs and'adapted to be engaged by the stationary catches 45 on the sides of the trough,'see especially Figs. 1, at, 6 and 7. In the preferred embodiment of the invention, these troughs are curved about the stationary pin 48 as a center, said pin forming the fulcrum 7 of a lever 49 articulately connected to a link 50, said'li-fik, in turn being articulately con-- nected to the plungendoortO. A catch 51 is provided for holding the lever 49 station ary to keep said plunger-doorsin proper 'position when closed. As a result of this construction when a fresh charge of paste is to be introduced the operator removes-the cover 4:2,draws back the plunger-door 40, puts a supplyof paste in the trough in front of it, replaces the cover,- swi'ngs the lever 49 to closed position and looks it there by catch 51.

In 'the best form of mach ne, the entlre trough is adapted to be thrown back to the.

position shown in dotted lines Fig. 7 to per mit the parts to be cleaned. The trough 1s pivoted upon a pin 52 at the slde of the cylinder,' which acts as a hinge. Said trough is held in closed or normal position by suitable locking means such as the lever 53 adapted to engage thetrough lug-54:.

The grid, which for the sake of illustration is selected as the object to be pasted, is indicated in'Fig. 9, althoughitvwill be understood that the object to be pasted may assume various forms. A holder adapted to this form of grid is shown separately in Fig. 8 and indicated by the reference numeral Guides 56, (see especially Figs. 1 and 6) are provided to guide the grid holder to the space between the paste wheels 14.

The preferred means for advancing the grid holder is the 'nut 60 which rides upon tated.

machine. It is desirable that the nut engage the screw from only one side, the remaining side being cutaway as shown in Fig. 4 to admit of said nut being lifted away from pushes the first grid holder on through the i the screw to thus permit it to be quickly retracted even though thescrew continues to rotate in a direction. to advance the nut.

A slotted lever 62 is fulcrumed at the stationary pin 63 as best shown in Figs. 1 I

and 6 and is also connected to said nut 60 and enables the. operator to manipulate the nut guides 56 as shown andis adapted to raise i the lever 62-and thuslift the nut clear of" the screwwhenithas approached theend of said screw. This automaticallyprevents breakageand relieves the operator of the close attention which would otherwise be requiredp Screw 61 is driven by means of a gear 65 thereon, as shown in Fig. l; this gear being driven by a worm 66 on the shaft 67. Said shaft is in gear connection with the band wheel 20- as best shown in Figs. 1 and 8.

Inyoperation, the operator first manipullates the'controllingvalve 32 in the pipe'32 in such manner as to lower the piston rod 26. This retracts the .plungers 23 in: the paste cylinders preparatory tothe introduction of. a supply of paste. The operator then removes the-trough covers 42 and retracts the plunger-doors 40 bymeans of'the levers-49 and places a charge of paste inthe troughs in front of said doors. He then replaces the trough covers and moves the doors to closed position, thus forcing a charge of paste into the cylinders behind the paste wheels 14. He also retracts the nut 60 by means of the lever 62, swinging the latter to the position shown 1n dOttQClllTlGS in Fig.

6. 'He then adjusts a grid holder in position as shown in dotted lines and inserts a grid into the holder. The machine isthen ready to be started. turned on it causes the paste wheels 14 to rotate and also causes the screw 61 to rotate to. advance the grid and grid holder;

Assoon as. the power is At the same time the operator manipulates the valve 32 to introduce the pressure medium into the cylinder 27 in such manner as to raise the piston rod 26 and thus move the plungers 27 1n such manner as to raise the piston rod 26 and thus move the plungers 23 toward the paste wheels l l-to sup ply paste to them and the grid. After the machine is thus started the operation is 85 read ly. A lifting cam 64m located in con- 'venient position preferably on one, of the practically continuous, until the supply of paste has been exhausted, whereupon the cylinders may be refilled and the operation repeated.
